FACING FOR WALLS.

QPIECIFIGATION forming part of Letters Patent No. 600,897, dated March 22, 1898.

Application filed December 13, 1895- Serial No. 572,076. (No model.)

To all whom it may concern.-

Be it known that I, KARL SIEBOLD, architect, of Gradderbaum, near Bielefeld, in the Kingdom of Prussia, German Empire,have invented new and useful Improvements in and Relating to Facings for Walls and other Structures for Securing the Same, of which the following is a specification.

My invention relates to a groove-and-tongue facing in which the facers are connected by grooves and tongues either with the backing or with each other or with the backing and also with one another.

The advantages obtained by this invention as compared with the mode of facing heretofore practiced, in which, according to the ordinary rules of the bond, the one-fourth and one-half facers are connected with the backing, are as follows: first, a considerable saving of facing material; second, a better protection of the wall than by the customary mode of facing, and, third, a saving of backing material.

As the mode of groove-and-tongue facing may be greatly varied according as it is carried out with horizontal or vertical tongues with or without special tongued backing, the following description has been divided into three main sections for the sake of clearness.

On the accompanying drawings several forms of execution of the new groove-andtonguefacing are represented.

Figures 1 and 1 show in perspective view and section the employment of asingle-form piece. Figs. 2" and 2 show in the same views a modification of the improvement. Fig. 3

shows in section the employment of two different stones for facing. Figs. at and 4: show in perspective View and section the employment of two other different facers. Figs. 5 and 5 show in sections of the bond-course and of the stretching-course two different facers. Fig. 6 shows in perspective View and section the combination of facing-stones and facing-plates. Figs. 6 and 6 show in the and 2 and 2 possess two suitable facing-surfaces. The tongue has a simple form and engages in a recess of the correspondingbackingstone. This recess is formed in Fig. 1 in the backing-stone c itself, while, according to Fig. 2*, it is formed by cutting ofi the corresponding stone of the bond-course d. The protection of the joint for the spandrel is obtained by alternating the facers relatively to the vertical joints of the backing.

In the two different-formed facing-stones e andf or g and h of Figs. 3, 4E, and 4 where each facer has only one facing-surface, the joint-forming edges '6 or 76 engage each. other fold-like, while at the same time the hookshaped form Z or m of the back side is lying in a recess of the backing. In the facingstones of Fig. 3 only the stone 6 and in those of Figs. 4 and 4 each has a hook-shaped fold. In the latter arrangement the folds m, of two facers, extend in opposite directions, so that the one from above and the other from below engage the stone n of the stretchingcourse. The interjacent cut off backingstone 0 of the bond-course has no groove. As the vertical and horizontal joints of these facers are alternated against those of the backing the latter is perfectly protected against moisture. The same effect is also in the arrangement of Fig. 3, in which the hookshaped fold Z of the facer e engages in a groove as well of the stretching-stonep as of the bondstone q. The flat facer f protects the joint formed by the stretching-coursep and the following bond-course.

From the two different-shaped facers r and s of Figs. 5 and 5 stone 4 is provided at the middle of its back side with a projection 0",

which is jointed into corresponding grooves of two backingstones. The plate-shaped facers fills the space between two facers r and engages with its lateral vertical tongues s in the lateral vertical grooves r of the facer r.

Similar to the above-described arrangement is that of the facers t and u of Figs. 6 and 6 5 but it differs advantageously from the same by the fact that fewer tongued backing-stones are needed and that when some precaution is taken these may be produced from ordinary stones by cutting.

In the modification according to Figs. 7 7 and 7 facers '0 are used which are provided with tongues and grooves and are inserted in the bond-course of the backing in such amanner that certain intermediate spaces remain. These intermediate spaces are filled up by pressed facing-plates to, which consistof a smaller portion cc and a larger portion .2 and have a height of two courses of the backing, so that the plate to protects a portion of the bond-course and a portion of the stretchingcourse of the backing. Each plate has at its sides tongues and grooves wherein tongues and grooves of portion w correspond with the tongues and grooves of the facer r, while the tongues and grooves of portion y serve for connecting with the parts of other plates to. The advantage of this constructional form lies in a great saving of facing material and in the very easy workof facing. This form of execution is also adapted for facing old houses because the small holes for the bondfacers can be put easilyin the backing. With regard to the constructional forms represented in Figs. 6 and? it may be observed that thesev are particularly adapted for producing ornamented facing, as shown as at m.

In the modification according to Fig. 6 the facing-plate u engages with the'facing-ston es t. This constructional form has the distin:

gui'shing feature that no special backingstones and little facing material are required and that a good protection of the joint is obtained by the peculiar connection of the facing-plates with the other facing-stones, for in this mode the bond-course is faced in the ordinary manner with one-fourth facingstones while the stretching-course is covered by facing-plates connected by tongues with the other facers.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

1. In facings for walls and the like, the combination of facing-stones inserted in the backing, with facing-plates connected with the stones by groove and tongue, substantially as and for the purpose set forth.

2. In facin gs for Walls and the like, the combination offacing-stones inserted in the bondcourse of the backing in such a manner that certain intermediate spaces remain, with facing-places filling up the intermediate spaces, and being connected with the stones by groove .and tongue, substantially'as and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two, subscribing witnesses.
